/** A debugging class whose main program may be invoked as follows:
 *      java gitlet.DumpObj FILE...
 *  where each FILE is a file produced by Utils.writeObject (or any file
 *  containing a serialized object).  This will simply read FILE,
 *  deserialize it, and call the dump method on the resulting Object.
 *  The object must implement the gitlet.Dumpable interface for this
 *  to work.  For example, you might define your class like this:
 *
 *        import java.io.Serializable;
 *        import java.util.TreeMap;
 *        class MyClass implements Serializeable, Dumpable {
 *            ...
 *            @Override
 *            public void dump() {
 *               System.out.printf("size: %d%nmapping: %s%n", _size, _mapping);
 *            }
 *            ...
 *            int _size;
 *            TreeMap<String, String> _mapping = new TreeMap<>();
 *        }
 *
 *  As illustrated, your dump method should print useful information from
 *  objects of your class.
